Ralph Boehme 3633027e49 rpcd_mdssvc: initialize POSIX locking ... Otherwise the posix_pending_close_db is NULL and we crash when trying to close a file descriptor: #4 /usr/lib64/samba/libdbwrap-samba4.so(dbwrap_parse_record+0xe) [0x7fbc5d05c8ae] #5 /usr/lib64/samba/libdbwrap-samba4.so(dbwrap_fetch_int32+0x38) [0x7fbc5d05d438] #6 /usr/lib64/samba/libsmbd-base-samba4.so(fd_close_posix+0x7b) [0x7fbc5e276f8b] #7 /usr/lib64/samba/libsmbd-base-samba4.so(+0x57900) [0x7fbc5e28a900] #8 /usr/lib64/samba/libsmbd-base-samba4.so(fd_close+0x68) [0x7fbc5e2b7ea8] #9 /usr/lib64/samba/libsmbd-base-samba4.so(+0x62608) [0x7fbc5e295608] #10 /usr/lib64/samba/libtalloc-samba4.so(_talloc_free+0x51b) [0x7fbc5d9f439b] #11 /usr/lib64/samba/vfs/fruit.so(+0xcac2) [0x7fbc45fcdac2] #12 /usr/lib64/samba/vfs/fruit.so(+0xcbdd) [0x7fbc45fcdbdd] #13 /usr/lib64/samba/vfs/fruit.so(+0xf603) [0x7fbc45fd0603] #14 /usr/lib64/samba/libsmbd-base-samba4.so(+0x56375) [0x7fbc5e289375] #15 /usr/lib64/samba/vfs/nothingtoseeherereally.so(+0x196c) [0x7fbc467f996c] #16 /usr/lib64/samba/vfs/streams_xattr.so(+0x51fc) [0x7fbc461e71fc] #17 /usr/lib64/samba/libsmbd-base-samba4.so(+0xade3a) [0x7fbc5e2e0e3a] #18 /usr/lib64/samba/libsmbd-base-samba4.so(create_conn_struct_cwd+0x44) [0x7fbc5e2e1cf4] #19 /usr/libexec/samba/rpcd_mdssvc(mds_init_ctx+0x2c3) [0x563fdac08f03] #20 /usr/libexec/samba/rpcd_mdssvc(_mdssvc_open+0x141) [0x563fdac0b4d1] The corresponding open is done as part of initializing a connection_struct object, where we chdir() and stat() the root path of the share. The stat() in vfs_fruit causes an expensive metadata request on the path which triggers an internal open of a pathref handle. Note that this only affects servers that have fruit:metadata = netatalk set, which is the default unfortunately.
